St. Tudfyl was one of
the many daughters of King Brychan Brycheiniog. She
was a good Christian and travelled across South Wales, founding churches
at Merthyr near Carmarthen and Llysworney near Cowbridge. While visiting
her aging father at what is now Merthyr Tydfil in Morgannwg, the palace
was attacked by a raiding party of pagans, either British or Saxon. Tudfyl
was killed in the raid and her distraught brother, Rhun, mustered a force
of men to pursue their attackers. They slew the majority of them in a
battle by the river crossing at Pont Rhun. Unfortunately, however, Rhun
himself was killed there at the very moment of victory. Tudfyl's feast day
is 23rd August.
